--- Comment #39 from MattS <matt@snowtrek.org> ---
On my Host OS unRAID 6.8.0, i440fx with seabios or OVFM FreeBSD just hangs =
on
boot. One of the unRAID developers (jonp) spent a little time on it, and was
also unsuccessful. It's possible that it's an unRAID specific issue. Not su=
re
at this point.

https://forums.unraid.net/topic/84692-freebsd-113-no-network-interface-afte=
r-upgrade/page/2/?tab=3Dcomments#comment-809306

I was able to get virtio NIC working on 12.1 with TommyP's patch. (Thank yo=
u!)

I'm not sure how to show this on unRAID, but VT/D is enabled and PCIe ACS

pciconf does not show any intel NIC device detected. (same with passed thro=
ugh
Intel NIC).=20

When I compile 11.3 kernel without NETMAP, I see NIC interface detected as
"none2@pci0:1:0:0", but still does  not work. (see attached)

See DMESG output screenshots. "em0: Unable to allocate bus resource: interr=
upt"
